DJ Accused of Sex Assault in Clarendon

A former Alexandria resident and DJ is accused of sexually assaulting an unconscious woman in Clarendon and videotaping the encounter.

Joseph Rivera, 34, has been charged with aggravated sexual battery in connection with the incident, which police say took place between 2:00 and 2:33 a.m. on December 26, 2010. According to police, Rivera sexually assaulted an unconscious 26-year-old woman in a vehicle in a parking lot somewhere in Clarendon.

The victim came forward after seeing news reports about Rivera, who last week was charged with numerous sex offenses by Fairfax County Police. Those charges include rape, aggravated sexual battery, animate object sexual penetration and two counts of unlawful filming; police say Rivera sexually assaulted several unconscious women and made videos of some of the assaults.

Rivera, formerly of 724 Four Mile Road in the Arlandria section of Alexandria near the Arlington border, was arrested in Las Vegas and is awaiting extradition.

The Arlington victim saw Rivera’s mug shot on the news and contacted police, Arlington Police spokesman Dustin Sternbeck said. Detectives showed her one of the videos he made to establish positive identification.

“The victim saw the news coverage and called police,” he said. “She was able to identify herself in one of the videos the suspect had taken.”

Rivera worked as a DJ at several D.C. area bars under the name Joey Flash. According to the Washington Post, one of the bars he worked at was A-Town Bar and Grill, in the Ballston area.

The bar was operated under a different name in 2010 and Sternbeck was unable to say whether Rivera had been working as a DJ the night of the alleged Dec. 26, 2010 incident.
